Airtac SED Double Rod Cylinder SED100X260
The AirTAC Airtac SED Double Rod Cylinder SED100X260 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 260mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X260
The AirTAC SED100X260 is a double-acting, double-rod ISO 15552 profile cylinder with a 100 mm bore and 260 mm stroke. A piston rod exits both end covers, meaning the annulus area is identical on extend and retract. Consequently, drive force is perfectly balanced at 3681 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean ISO 15552 dimensional interchange footprint.
This unit lacks the -S magnet option, so it cannot host CMSE or DMSE position sensors directly. However, the rear rod protrusion is highly valuable for mounting external cam flags or driving secondary mechanisms. Adjustable air cushions at both ends absorb kinetic energy near stroke limits, though they are deceleration bumpers, not locking brakes.

| Stroke | 260 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 kgf |
Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SED Double Rod Cylinder SED100X260 Is Used
Servo Press Platen Drive
Drives a 100-ton servo press platen where 5153 N of equal both-way force prevents platen skew during high-speed stamping.
Pallet Transfer Pusher
Shifts heavy pallets on an assembly line, using the rear rod to trip an external mechanical flag at full retract.
Web Guide Mechanism
Aligns heavy steel web rollers; the twin-rod anti-rotation特性 keeps the 25 mm rod perfectly straight under 3681 N load.
Is the Airtac SED Double Rod Cylinder SED100X260 the Right Cylinder?
Selecting this 100 mm bore yields 3681 N of bidirectional force at 0.5 MPa (5153 N at 0.7 MPa, maxing at 751 kgf). If you need less push, the 80 mm SED neighbor provides 2268 N at 0.5 MPa. For heavier demands, stepping up to the 125 mm bore yields 5734 N at 0.5 MPa. Because the 260 mm stroke exceeds 300 mm only marginally, you should still evaluate external guide rails to prevent rod side-loading and premature seal wear.
Choose this double-rod SED over a single-rod SE when your machine requires anti-rotation stability, twin-side load driving, or a rear-rod cam for external tracking. Remember that a standard SED cannot hold position on air loss—the piston will drift. For fail-safe holding, specify a BSED double-rod lock cylinder or an external pilot-operated check valve. When replacing an ISO 15552 unit, match the 100 mm bore, 260 mm stroke, PT1/2 port, and mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED100X260 FAQ
Because a rod exits both ends, the effective area is identical in both directions. The SED100X260 outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa. Extend and retract forces are perfectly equal.
The twin rods offer superior anti-rotation guidance and allow the rear rod to drive a secondary mechanism or cam flag. It also shares the ISO 15552 mounting interface, but omits FB, CA, CB, and CR mounts, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2.
